The heavy-duty JL: Hi-Lift Jack Tailgate Mount Kit provides a safe, quiet, and secure mounting point for a Hi-Lift Jack. The 3/16”-thick laser cut, and powder coated bracket bolts to either our Alpha HD Hinged Spare Tire Carrier or the factory tailgate for unshakable stability. This bracket also incorporates a built-in CB antenna mount as well as an off-road flag mount for those sand dune trips. Provides clearance for most 37” tires. The RotopaX Hi-Lift Jack Mount Kit (# 4838255 — sold separately) allows you to mount RotopaX containers to the Hi-Lift Jack leg.
